ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for
8.3L engines. The designation of ENERGY CON-
SERVING is located on the label of an engine oil con-
tainer.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have
been adopted to aid in the proper selection of engine
oil. The identifying notations are located on the label
of engine oil plastic bottles and the top of engine oil
cans (Fig. 4).
ENGINE OIL ADDITIVES/SUPPLEMENTS
The manufacturer does not recommend the addi-
tion of any engine oil additives/supplements to the
specified engine oil. Engine oil additives/supplements
should not be used to enhance engine oil perfor-
mance. Engine oil additives/supplements should not
be used to extend engine oil change intervals. No
additive is known to be safe for engine durability and
can degrade emission components. Additives can con-
tain undesirable materials that harm the long term
durability of engines by:
•Doubling the level of Phosphorus in the engine
oil. The ILSAC (International Lubricant Standard
Approval Committee) GF-2 and GF-3 standards
require that engine oil contain no more than 0.10%
Phosphorus to protect the vehicles emissions perfor-
mance. Addition of engine oil additives/supplements
can poison, from the added sulfur and phosphorus,
catalysts and hinder efforts to guarantee emissions
performance to 100,000 miles.
•Altering the viscosity characteristics of the
engine oil so that it no longer meets the require-
ments of the specified viscosity grade.
•
Creating potential for an undesirable additive com-
patibility interaction in the engine crankcase. Generally
it is not desirable to mix additive packages from differ-
ent suppliers in the crankcase; there have been reports
of low temperature engine failures caused by additive
package incompatibility with such mixtures.
ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT
STORE IN OPEN OR UNMARKED CONTAINERS.
WASH SKIN AND CLOTHING THOROUGHLY AFTER
COMING IN CONTACT WITH ETHYLENE GLYCOL.
KEEP OUT OF REACH OF CHILDREN. DISPOSE OF
GLYCOL BASE COOLANT PROPERLY, CONTACT
YOUR DEALER OR GOVERNMENT AGENCY FOR
LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN
THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN
ENGINE COMPARTMENT RELATED SERVICE IS
PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene Glycol based coolants
is not recommended, as they provide less freeze
protection and less boiling protection.
The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves and
engine block. Then coolant carries the heat to the
radiator where the tube/fin radiator can transfer the
heat to the air.
The use of aluminum cylinder blocks, cylinder heads,
and water pumps requires special corrosion protection.
MopartAntifreeze/Coolant, 5 Year/100,000 Mile For-
mula (MS-9769), or the equivalent ethylene glycol base
coolant with hybrid organic corrosion inhibitors (called
HOAT, for Hybrid Organic Additive Technology) is rec-
ommended. This coolant offers the best engine cooling
without corrosion when mixed with 50% Ethylene Gly-
col and 50% distilled water to obtain a freeze point of
-37°C (-35°F). If it loses color or becomes contaminated,
drain, flush, and replace with fresh properly mixed cool-
ant solution.
